F is for Fartlek

So what the heck is a fartlek? Fartlek is Swedish for “speed play.” As a runner I am super familiar with this word and yes it still makes me laugh when I say it out loud. Unlike tempo and interval workouts the fartlek is unstructured. After you warm up, you play with speed by running faster for short periods of time followed by easy running for recovery. You can easily work this in during a training run or fun run. The goal is just to keep it free and unpredictable while pushing yourself during those speed bursts.
